Abstract: A method and apparatus are disclosed for communication in a Millimeter Wave Hotspot (mmH) backhaul system which uses mesh nodes. A mmH mesh node may receive a control signal which includes a total number of available control slots. The mesh node may determine the number of iterations of a resource scheduling mechanism that can be made during the time period of all available control slots, based on the number of neighbor nodes for the mesh node. Further, the mesh node may receive control slot information, including information about traffic queues and priorities. The mesh node may then perform resource scheduling using the resource scheduling mechanism based on the currently received control slot information and control slot information received in previous iterations of resource scheduling. The mesh node may also adjust a preamble based on a time between a last packet transmission and a current packet transmission to a neighboring node.

Abstract: An example method facilitates verifying behaviors, functionality, and user interface display screens of a post-upgrade software system by comparing output thereof with a pre-upgrade software system. The example method includes accepting a first signal from a user input device to identify, at least in part, a first set of pre-upgrade output data items from the pre-upgrade software system; accepting a second signal from a user input device to identify, at least in part, a second set of corresponding post-upgrade output data items from the post-upgrade software system; and performing a consistency validation check between corresponding output data items in the first set and the second set. Accordingly, output data items in an upgraded system are readily validated against a pre-upgrade system. Plugins, as part of an upgrade verification tool, may implement specific tests. This enables enterprise software customers to automate their on-premise upgrade validation processes and to choose tests.
